Zipp 303 broken rim replacement options

[Zeffer]

Hi guys
Got a set of oldish 303 tubbies with cracked/damaged rims and considering replacing only the rims with 'aftermarket' clincher rims. Note the proposed conversion from tubby to clinshr.
Spokes and hubs are still good.

Also noted that the rims are 18/24 and not the usual 20/24 configuration.

Can I buy 30mm carbon 18/24 rims and merely replace the hoops or I am gonna miss something crucial?

Unless the spoke lacing pattern is weird, then yes, you can just buy new rims and have them built onto your hubs.

If the rim depth isn't identical, you may need new spokes.

Shout if you need help sourcing rims - I am the distributor for Nextie rims in South Africa and I can help if needed.

I can obviously also rebuild the wheels for you.
